NFPA 288水平安装的防火门测试 –适用范围
本标准适用于各种材料和结构类型的地板防火门组件，该组件水平安装在耐火等级地板系统的开口中，以阻止火势通过。
根据该测试方法进行的测试证明了地板防火门组件在测试期间的性能。但是，此类测试不应解释为确定地板防火门组件在着火后是否适合使用。
This standard shall apply to horizontal fire door assemblies of various materials and types of construction that are installed in openings of fire resistance- rated floor systems or roofs to retard the passage of fire.
Tests made in conformity with this test method demonstrate the performance of horizontal fire door assemblies during the test exposure; however, such tests shall not be construed as determining the suitability of horizontal fire door assemblies for use after their exposure to fire.
